Intestinal adenomatosis in the pig: a possible relationship with a haemorrhagic enteropathy.

An outbreak of a haemorrhagic enteropathy in a closed herd of pigs was followed by the appearance, in the same herd, of cases of intestinal adenomatosis. This paper now draws attention to similarties in the mucosal pathology which are present in the two conditions. The affected tissue showed substantial epithelial proliferation and retrospective electron microscopic studies of material from both these entities revealed the presence of bacteria of similar morphology within the cytoplasm of these epithelial cells.
